New diffraction phenomenon of acoustic waves. A novel asymmetric diffraction has been achieved using a nano-patterned array of ferromagnets. This demonstration arises from a unique interaction ...

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...

The wavelength is unchanged after diffraction. A gap width similar to the wavelength of the waves passing through causes a lot of spreading, eg sound waves passing through a doorway. A gap width ...

The goal of the current project is to open a new field of research by realizing the first diffraction experiments of atomic matter waves through crystalline 2D membranes like graphene. Such ...
